perf trace: Add filter Suppport
Add a new option "--filter <filter_str>" to perf record, and it should be right after "-e trace_point": #./perf record -R -f -e irq:irq_handler_entry --filter irq==18 ^C # ./perf trace perf-4303 ... irq_handler_entry: irq=18 handler=eth0 init-0 ... irq_handler_entry: irq=18 handler=eth0 init-0 ... irq_handler_entry: irq=18 handler=eth0 init-0 ... irq_handler_entry: irq=18 handler=eth0 init-0 ... irq_handler_entry: irq=18 handler=eth0 See Documentation/trace/events.txt for the syntax of filter expressions.
